Opis:
The Polish Financial Supervision Authority (hereinafter: KNF) is the key element of the economic security system of the Polish State. By establishing the KNF, the Polish legislator applied the concept of integrated financial supervision (covering bank supervision, insurance supervision and capital market supervision) located outside the central bank. The KNF has been vested with a broad mandate, including powers to supervise authorised entities. However, the scope and nature of measures available to the KNF in the prevention of economic crime are determined by the institutional position of the KNF, which has not been established as a law enforcement authority or a uniformed or special service but rather an institution engaged in the fight against economic crime by providing expertise, supporting other state services specialised in this area. The KNF and the Office of the Polish Financial Supervision Authority (hereinafter: UKNF) actively support, among others, the police units that fight crime in the financial market and work to increase the economic security of the Polish State. Therefore, it is imperative to ensure broad and efficient cooperation between the police and the KNF. However, such collaboration must not be limited to relations between the institutions’ management; it should also involve, as far as possible, working and operational activities carried out at both institutions by individuals responsible for day-to-day tasks. This paper provides a closer perspective on the formal and organisational framework of said cooperation and discusses its examples.

Opis:
Additive manufacturing is a technology of great interest for biomedical engineering and medicine since it enables to mimic natural structures. The 3D printouts require post-processing to ensure desired surface properties and interaction with living matter. The presented research focuses on novel approaches involving plasma treatment of Ti6Al4V scaffolds obtained by Direct Metal Printing. Solid samples and scaffolds of two various geometries were treated in atmospheres of pure argon, argon and oxygen or pure oxygen. The effect of post-processing was evaluated with scanning electron microscopy, measurements of mass, and surface roughness. In all the examined cases the proposed post-processing method reduces the amount of loosely bonded powder particles remaining after printing. The changes of mass before and after the treatment are much lower than in the case of popular wet chemical methods. The character of undergoing post-processing depends on the process atmosphere resulting in physical etching or the combination of physical etching and chemical oxidation. The action of argon or argon/ oxygen plasma reduces mass to the level of only 1% while by use of pure oxygen atmosphere even the slight increase of the overall sample mass is observed. The plasma etching was successfully introduced for the treatment of titanium 3D printouts to minimize the detachment of powder particles. That method not only is much softer than chemical etching but it can also lead to specific surface structurization that may be beneficial regarding medical applications of such printouts.

Opis:
Hydrogen storage for the purposes of the automotive industry in a form other than under high pressure or cryo conditions has been under careful investigation by researchers over past decades. One of the arising methods is the usage of powdered/granulated beds that contain metal hydrides and/or carbon materials to take advantage of the “spillover” phenomenon. Handling and characterization of such material can be troublesome, which is why the experimental setup needs careful investigation. The apparatus for the analysis of hydrogen sorption/desorption characteristics has been successfully designed and described based on the constructed unit within the scope of this article. The full functionality of that setup covered fuelling the bed as well as the examination of sorption/desorption potential. Moreover, the proposed experimental device can clarify many uncertainties about further development and optimization of hydrogen storage materials.
